IMPROVEMENT IN CULTiVATOR-S.

Specification forming part of Letters Patent No. 36,948, dated November1S, 1862.

To alt whom it may concern.:

Be it known that we, B. FURNAS and G. FURNAS, of Ononwa, in the countyof Louisa and State ot Iowa, have invented a new and ImprovedGultivator; and we do hereby declare that the following is a full,clear, and exact description ot' the same, reference being had to theaccompanying drawings, making a part of this specifica-tion, in which-Figure lis a side sectional view of our invention, taken in the line mx, Fig. 2. Fig. 2 is a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention relates to an improvement in that class of cultivators inwhich a lateral as welljas an up and downv adjusting movement is allowedthe shovel or plows.

rllhe invention consists in a novel means which is employed foroperating the shovels or plows, whereby the latter are placed under thecomplete control ofthe driver or operator and made to follow thesinuosites ot' the rows of plants, and also rendered capable of beingraised and lowered with the greatest facility, so as to plow therequired depth, the several parts being also so arranged that they maybe adjusted to snit the driver-to t'avor the most convenient operationof them.

To enable those skilled in the art to make and use our invention, wewill proceed to describe it with reference to the drawings. A representsa bar, to which the axle B of two wheels, G C, is attached. The endsofthe axle B are bent downward, so that the arms a a may be below thebar A, and thereby admit of the frame ot` the machine beingsufficiently* elevated to pass over the plants under culti vation.

D is the draft-pole ofthe machine, the back end of which is secured tothe bar A at its center, and to I:he draft-pole, at some distance fromits back end, there is secured transversely a bar, E, which has apendant, F, at or near each end of it. The pendants F F have each aseries of holes, af, made through them from their back to their frontsides, and in any ot' these holes loops or links b are fitted, as shownclearly in Fig. 1. These loops or links b serve to secure bars G G tothe pendants, and admit ot said bars being raised and lowered to acertain extent at their back parts, and also admit. of them being movedlaterally.

To the pendants F F there are also attached two bars, H H', one to each.These bars are attached to the pendants by pins c, which pass throughany ot" a series of holes, d, made laterally through the pendants or-ina direction transverse with the machine. The bars H H also pass throughloops or bearings ce, attached to the under side ot' the bar A, and saidbars H H( extend a considerable distance back of the bar A and have thedriver-s seat I placed upon them.

The seat I is secured by a bplt,f, to the bar H, but is not attached orpermanently secured to the other one, H. It simply rests upon it, andmay be secured by any suitable catch or fastening. The object of this isto admit of the driver readily placing himself upon the seat, which isdone by merely drawing the free or disengaged end out from the bar H',so that he can pass in between the bars H H and then place himself' uponit after it is properly adjusted in position on bar H', thereby savingthe trouble of climbing over the seat, which would have to be done wereit permanently attached to both bars H H.

The bars G G are the plow-beams, and each has two shovels or plows, J J,attached to it by means ot' curved or bent standards ff, the standardsofthe foremost plows being curved or bent inward, and the standards ofthc back plows being bent or curved outward. By this means the frontplows are brought nearer together than the back ones, as will beunderstood by referring to Fig. 2. Each plow-beam G has a treadle, K,attached to it by a pin or holt, g. The use of these treadles will bepresently shown.

Lis a metal rod o r bar, which is bent so as to forni two vertical partsor uprights, h li, and a horizontal upper part, i. The lower ends of thenprights It h are secured to the bar A, and they are each bent so as toform a loop or bearing, j, at about their centers. In each bearing jthere is fitted a bar, M, the back ends ot' which are connectedbyacurved cross-piece, N, which serves as a bearing for the back oi' thedriver on seat I. The front ends ofthe bars M M are connected by cordsor chains k 7c to the plowbeams G G, and the driver by simply raisingthe uprights.

and lowering the bars M, which may be readily done by relieving thecross-piece N of the pressure of his back and then pressing with hisfeet on the bars G, when the plows are to be lowered, and depressing theback parts of said bars when the plows are to be raised.

The treadles K K are each connected to the horizontal part t' of the barL by a cord or chain, l. These cords form fulcra for the treadles andcause the beams Gto be elevated when the former are acted upon by thefeet of the driver. Thetreadles thus arranged serve as a very convenientmeans for elevating the beams and plows, and in certain cases arepreferable to the bars M for that purpose.

Each plow-beam G has an upright, O, attached to it. These uprightsextend upward through guides in m connected to the horizontal part/ofthe bar L, and the plow beams are sustained at a suitable height by pinsn n, which pass through the uprights O above the guides fm. The uprightsO O are connected by a crossbar, P, having a series of holes made in itnear each end, through whichpins 0 pass into By adjusting these pins inditferent holes in the har P the beams G may be secured at a greater orless distance apart', as

4,may be desired. The plow-beams G may hc 'attached higher or lower tothe pendants F F, and the same lmay be said of the bars H H.4 The seatI, therefore, can be adjusted higherl or lower, so that the driver canactuate the Vbeams or their treadles conveniently with his. v vfeet.

The plows are moved laterally under the action of the feet of thedriver, the uprights O being allowed to work freely in the guides m fm,and either plow may be depressed or forced down, irrespective of theother, and one furrow may consequently be made deeper than the other,and this very frequently requires to be done.

Having thus described our invention, what we cla-im as new, and desireto secure byLetters Patent, is-

l. The bars H H', connected at their front ends to the pendants F F, andprovided at their back ends with the drivers seat I, in combination withthe bars M M, connected at their back ends with the cross-piece N, andattached to the plow-beams G G by the cords or chains 7c 7c, allarranged substantially as and for the purpose herein set forth.

2. The treadles K K, when attached to the plow-beams G G, and connectedto the cords or bar L by the cords or chains l, as and for the purposeherein set forth.

3. The uprights O O, attached to the plowbeams G G, titted in the guidesm m of thed bar L, and connected by the bar P, substan- A,tally as andfor the purpose specified.
